The good thing about morale is that it doesn't have to be the same for different people. It's not an absolute value. You can live up to your high morale standards and watch ads (which sounds a bit odd). Other people think differently.

Other people like me think we are morally bound to ignore ads as much as possible because we think they destroy a healthy capitalism and are misused to track people and distribute malware. Therefore I use an ad-blocker.

But that's only a side note. In the internet your argument is invalid because I don't know in advance whether a website uses ads or not. To discover that I would have to visit that site without an ad-blocker and let them serve ads without warning. And that would be unacceptable.

The solution for that problem is the various websites either use paywalls or detect ad-blockers and don't provide content when one is in use. In this case we really have an agreement. If I turn off my ad-blocker I'm allowed to watch the content, otherwise I'm not.

But I never ever had the desire to see content which has been hidden behind an ad-blocker blocker.
